METHOD OF MAKING RIVET-CLOTH.

Specification of Letters Patent.

Original application filed November 20, 1912, Serial No. 732,427.Divided and this application filed March To all whom it may concern Beit known that I, Jnnonn T. Rtrrnuntnc,

and useful Method of Making Rivet-Cloth,

of which the following is a specification.

This is a division of my application Serial No. 732,427, filed November20, 1912.

This invention relates to the immuli'acture ot a cloth without pilehaving when produced on the loom, perforations therethrougl'i arrangedat intervals both longitudinally and across the goods.

The principal type of fabric to which this invention relates is thesoazalled rivetcloth which is used in the manufacture of rubber tires,but it is capable of use for the production of any such fabric.

The invention involves im1n'ovcments in the method of making the rivetcloth in such a manner that it will be a complete article as it comesfrom the loom without the necessity of picking out all the warp andfilling threads occupying those spaces which are to be left vacant.

Reference is to be had to the accompanying drawings, in which- Figure 1is a plan of the fabric on the loom showing it as it appears immediatelyafter the weaving operation; Fig. 2 is a similar view of the fabricafter the rods:

are withdrawn and the left-hand edge trimmed oil, and Fig. 3 is asimilar view of the completed rivet cloth.

So far as I am aware rivet cloth has been manufactured heretofore byweaving a continuous length of cloth and having the filling.

inserted continuously from end to end of a continuous warp, but the warpand filling in the places where the openings are to appear are of adifferent color from the main body of the fabric, and after the fabricis woven they are drawn out. This is an expensive method, involving notonly a slight complication in the weaving, but especially takingconsiderable time in the drawing out of the colored threads, and thewasting of these threads. This invention is designed Serial No. 756,408.

chiefly to avoid this waste by making the fabric originally with theopenings therein, so that the threads will not have to be cut and drawnout, or at least only two will for each space, and also to provide asimple method of Freeing the threads which are drawn out in order toleave only a firm Fabric.

Referring now to the drawings, for the purpose of producing the rivetcloth or other fabric of a similar nature in a cheap and expeditiousmanner, the following arrangement is provided. First, the warp A is arranged to consist of a plurality of sections ol main warp threads (1arranged in a plurality of series of a given number of threads each, sayfor example eight. These threads are separated by spaces substantiallyoi. the same width as the width of a section of these warp threads. Atthe edges of these sections are binding warp threads a which are smallerthan the main warpthreads and thus are capable of being more closelywoven in and perform a Function similar to the sclvage in that they holdthe edges of the sections. Outside the main warp are two warp threads(1%, the purpose of which will be described hereinafter. The filling iswoven into these warps in the usual manner the usual roller chain (notshown) being employed to operate the jacks, but one of the jacks whichoperates only after a definite number of picks are made, as for exampleten, is arranged so as to be actuated at regular intervals, as forexample, at every tenth pick in the embodiment illustrated in thedrawings. In other words when ten picksot' filling have been inserted inthe warp, a connection will be actuated to move the shipper handle andthus stop the loom. Then the operator inserts a rod 25 into the warp asindicated in Fig. 1. Each of these rods has a book 26 on the end.Connected with the main or crank-shaft means is provided to engage ahook 26 of one of the rods 25 at regular intervals during the operationof the loom. These parts are so timed that as the cloth 'lj'ecds overthe breast beam these means will come into engagement with therespective hooks 26 when these hooks reach a predetermined point. Inthis case then these members will operate once for every ten picks todraw out each rod 25.

Referring especially to Fig. 1, it will be seen that the filling B iswoven into the fabric to form the usual filling strand Z across thesame, but that just before the loom stops, that is 011 the ninth pick inthis case, a loop .7) is formed on one side of the fabric around theside warp thread a It is then woven into the fabric and extends out onthe other side at 6 around the other strand o of the rod 25 which hasbeen inserted and is woven in again forming a second loop 6 on the otherside. It then continues to be woven in for the desired number of picks,for example, ten, when the loom again stops and the next rod 25 isinserted. It will be understood, of course, that these rods 25 can beinserted by the means which are em ployed for introducing pile wires incarpets, on carpet looms and the like, without departing from the scopeof the invention as expressed in certain of the claims and in fact sofar as the method is concerned can be both inserted and withdrawn byhand. The fabric as thus produced on the loom itself thus assumes theform shown in Fig. 1. Now as the fabric passes on, and preferably beforethe rods 25 are withdrawn, it is caused to come into contact with afixed or adjustable blade at the side on which the loops 6 are located.This blade is located directly at the edge of the main warp so as tosever the loops b of the filling. This leaves the fabric when the rodsare withdrawn in the form shown in Fig. 2.

F or the purpose of insuring that the filling actually remaining in thefabric shall be firmly woven therein and not likely to spread out in therectangular spaces to be left, an extra filling thread 6 is left on eachside of each space. These are the ones which are now connected with thestrands b and as their opposite ends are clipped it will be obvious thateach pair of them can be drawn out simultaneously with great rapidityand without interfering with the strength and firmness of the fabric. Inthis way the expensive operation of clipping and pulling out by hand allthe threads to form spaces in the cloth, is, for practical purposes,eliminated and this reduces the cost of the material very essentially.On account of having the end strand that comes next to the rod drawn outthe filling that remains is firm. secure and uniform. In this way thiskind. of fabric is inexpensively manufactured and is made uniformthroughout as the hand operations are dispensed with. At the same time afabric is secured which is an improve- Then it passes to the other sidement over the old hand-drawn rivet cloth in the particulars abovespecified.

Although I have illustrated and described only a single embodiment ofthe invention I am aware of the fact that modifications-can be madetherein by any person skilled in the art without departing from thescope of the invention as expressed in the claims. Therefore I do notwish to be strictly limited to the precise order of steps herein shownand described, but

lVha-t I do claim is l. The improvement of the art of making wovenfabrics without pile which consists in inserting smooth uniform rods atintervals in the warp parallel with the filling, after weavingwithdrawing said rods to leave a space between two adjacent sections offilling, and thereafter drawing out the thread on each side of eachspace.

2. The improvement in the art of weaving fabrics which consists ininserting rods parallel with the filling at intervals in the warp,weaving the filling thread adjacent to each rod to a point beyond theedge of the fabric on one side and the next thread on each side beyondthe other edge of the fabric, with drawing the rods, cutting the lastnamed extendingfilling threads at the edge of the fabric, and thendrawing out the first named extended filling threads from the other edgeof the fabric.

3. The improvement in the art of making fabrics which consists inproviding a warp having two threads at a distance from the main body ofthe warp, inserting filling in the main body of the warp in a series ofsections, inserting rods in the warp between each two of said sections,extending the threads of the filling at one end of each rod and on bothsides thereof beyond the edge of the main body of the warp and aroundsaid side thread thereof, extending the other ends of both of saidthreads beyond the other edge of the main body of the warp and aroundthe other side thread thereof and back into the fabric, withdrawing therods, cutting the last named extending filling threads at the edge ofthe main body of the warp, and drawing out the pairs of first namedextending filling threads from the main body of the warp.

t. The improvement in the art of weaving fabrics, which consists inproviding a warp having a main body divided into sections with a freespace between each two sections, and two side warp threads at a distancefrom the main body of the warp, inserting filling in the main body ofthe warp in a series of sections spaced apart, extending the threads ofthe filling beyond the edge of the main body of the warp and around theside thread thereof, extending the other ends of both of said threadsbeyond the other edge of the main body of the warp and In testimonywhereof I have hereunto set around the other side thread thereof and myhand, in the presence of two subscribing back into the fabric, cuttingthe last named witnesses.

extending filling threads at the edge of the JEROME T. RUTLEDGE. mainbody of the Warp, and drawing out \Vitnesses:
